為什麼我無法將圖形放置在我想要的位置？

Question

我有一些文字，之後我想插入一個圖形。文字幾乎在第二頁上完成，所以我想將圖形放在第三頁的頂部（就在文字之後），但我不能。我在這裡閱讀了放置命令：http://en.wikibooks.org/wiki/LaTeX/Floats,_Figures_and_Captions我嘗試了所有不同的選項（即 \begin{figure}[t!], \begin{figure}[t], \begin{figure}[b], \begin{figure}[h], ...）但該圖仍位於第三頁中間的相同位置。我希望它位於頂部。我缺什麼？這是代碼：

Answer 1

就目前情況而言，您的文件不包含足夠的文本，因此 LaTeX 無法將圖形放置在頁面頂部。在第一頁上，頂部的浮動被禁止。沒有第二頁（文字）。因此，當圖形留在文件末尾時，LaTeX 會盡一切努力來放置它：它將它放在浮動頁面上，預設情況下，這意味著浮動在頁面上垂直居中。

如果圖形後面有更多文本，則不會發生這種情況：

\usepackage{amssymb,mathtools}% fixes/enhancements for amsmath (loads amsmath)

如果您希望圖形居中，請\centering在環境的開頭新增figure。

如果這是文件的末尾，您可以\newpage\vfill\mbox{ }在末尾添加以強制創建一個新的空白頁面，以使圖形浮動到頂部。

Answer 2

\usepackage{float}

\begin{figure}[H]

這將迫使 LaTex 將您的圖形放置在您想要的位置。
